Python: Get a list of dates between two dates

Last update on December 21 2024 07:27:50 (UTC/GMT +8 hours)

Write a Python program to get a list of dates between two dates.

Sample Solution:

Python Code:

# Import the timedelta and date classes from the datetime module
from datetime import timedelta, date

# Define a function named daterange which generates a range of dates between date1 and date2
def daterange(date1, date2):
    # Iterate over the range of days between date1 and date2
    for n in range(int((date2 - date1).days) + 1):
        # Yield each date within the range
        yield date1 + timedelta(n)

# Define the start date
start_dt = date(2015, 12, 20)
# Define the end date
end_dt = date(2016, 1, 11)

# Iterate over the range of dates generated by the daterange function
for dt in daterange(start_dt, end_dt):
    # Print each date in the format YYYY-MM-DD
    print(dt.strftime("%Y-%m-%d"))

Output:

2015-12-20

Explanation:

In the exercise above,

• The code imports the "timedelta" and "date" classes from the datetime module.
• It defines a function named "daterange" which generates a range of dates between 'date1' and 'date2'.
• Inside the daterange function:
• It calculates the number of days between 'date1' and 'date2'.
• It iterates over the range of days using a "for" loop.
• It yields each date within the range by adding 'n' days to 'date1'.
• It defines the start date as December 20, 2015.
• It defines the end date as January 11, 2016.
• It iterates over the range of dates generated by the "daterange()" function using a "for" loop.
• Inside the loop, it prints each date in the format YYYY-MM-DD using the "strftime()" method to format the date.
